Deleting a Class

To delete a class from the knowledge base:

  1. Highlight the class you want to delete in the Class Relationship pane.
  2. Click the icon from the class buttons or click the right mouse button and choose Delete selected class from the cascading class menu.
  3. You will be prompted for confirmation. Click OK.

To delete multiple classes:

  1. Highlight one or more classes in the Class Relationship pane. To highlight multiple classes, hold down the Ctrl key while clicking each class. To highlight a range of classes, click the first class, then hold down the Shift key and click the last class in the range.
    You cannot use the cascading menu to delete multiple classes.
  2. Click the icon from the class buttons. You will be prompted for confirmation. 

Deleting a class deletes the class and all of its subclasses. Once a class has been deleted it cannot be recovered. 

However, if you close Protégé-2000 without saving changes, you will revert to the last saved version. If you have made extensive changes to your project during the current session, you may wish to save before deleting classes. To do this, select Save from the Project menu. 

Classes cannot be deleted if they either are a system class or are included from another project. The class icon to the left of the class indicates the class type. See Including a Project for information about project inclusion.
